Christina Aguilera’s “Fall In Line” and Clean Bandit’s “Solo” both feature Demi Lovato.
Both also debut on this week’s edition of the Bubbling Under Hot 100.
“Fall In Line” starts at #1 on this week’s edition of the chart, while “Solo” grabs #7.
The Bubbling Under Hot 100 ranks the Top 25 songs that have yet to appear on the actual Hot 100.
Like the main chart, it determines positions based on combined activity from sales, streams and radio airplay.
Both songs generated ample activity on the sales front. “Fall In Line” improves to #17 on this week’s Digital Song Sales chart (after debuting at #39 last week), while “Solo” grabs #33.
